Photo Circulating tumor cells (CTC) are cells that are circulating in the blood which are shred either from primary tumor site in benign state or metastatic region. The NanoVelcro CTC Chip, a device made out of a patterned silicon nanowire substrate (SiNS) and an overlaid polydimethylsiloxane (PDMS) blender. There are four generations of NanoVelcro CTC tests created over the previous decade for an assortment of clinical utilities. The first gen NanoVelcro chips, made from silicon nanowire substrate (SiNS) and microfluidic blender, and were made for identification of CTC. The second gen NanoVelcro chips (i.e., NanoVelcro-LMD), in light of polymer nanosubstrates, were produced for single-CTC isolation which is related to the utilization of the laser microdissection (LMD) procedure. By grafting thermoresponsive polymer brushes onto SiNS, the third generation thermoresponsive NanoVelcro chips have exhibited the selection, capture and release of CTCs at 37°C and 4°C respectively, along these lines taking into consideration rapid CTC purging while at the same time keeping up with cell suitability and molecular integrity. Manufactured with boronic corrosive joined leading polymer-put together nanomaterial with respect to chip surface, the fourth gen NanoVelcro Chips (Sweet chip) had the option to filter CTCs with all wellpreserved RNA records, which could be utilized for downstream examination of a several cancer specific RNA biomarkers.
